Rinse Mussels under cold water to clean.
Mussels have “beards” that stick out of the shell. Most of the time this is already removed when you buy them in the supermarket. If you come across some that have beards just pull it backward to remove.
Check Mussels as you are rinsing them for broken shells and cracks and discard those. If mussels are really dirty you may need a scrub brush but this is normally not the case.
Now it is time go over to your Instant Pot and hit the SAUTE button an put it on the “normal” setting. Remove the lid and wait for the screen to say “HOT”
Add butter and olive oil to pan and wait for mixture to get hot. Once hot add the shallots and let saute about 2 minutes and then add garlic and saute about 1 minute more until fragrant.
Then pour in wine and stir. Let it cook down for a minute then add chicken broth and stir. Add about half of the parsley and scallions and hold on to the other half for garnish.
Add mussels to the Instant Pot and stir slowly to coat with broth. Put lid on Instant Pot and turn valve to “Seal.”
Hit Cancel on your Instant Pot and then hit MANUAL PRESSURE COOK Button and set for HIGH pressure.
Set Timer for 3 MINUTES.
When cook time is complete do a QUICK RELEASE by opening valve with a wooden spoon being careful not to get burned.
Remove lid from Instant Pot
Remove mussels from Instant Pot to a Bowl and sprinkle with leftover scallion and parsley garnish. Serve with crusty bread to soak up all the yummy garlic sauce.
